Turning a breakout open-source project into a company would be the wrong move -- joining a lab reaches everyone faster than building another large company.
Yes, I could totally see how OpenClaw could become a huge company. And no, it’s not really exciting for me. I’m a builder at heart. I did the whole creating-a-company game already, poured 13 years of my life into it and learned a lot. What I want is to change the world, not build a large company and teaming up with OpenAI is the fastest way to bring this to everyone.

MCP servers are worth removing outright: an agent reading the code directly is faster, and pollutes its context less, than one that can reach for a tool unasked.
Even removed my last MCP, since Claude sometimes would go off spinning up Playwright unasked when it could simply read the code - which is faster and pollutes the context less.

Tests written by a model in the same context as the change are what find the bugs; the automated tests left behind are the lesser product.
Bigger changes always get tests. Automated ones usually aren’t great, but the model almost always finds issues when you ask it to write tests IN THE SAME CONTEXT. Context is precious, don’t waste it.

Background agents do not work for real development, because steering a model as it drifts is the job, and you cannot steer what you are not watching.
Still don’t see how this could be moved to background agents. I steer the models a lot as I notice them drifting off - that’s much harder if they run in the background.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.
